<dd>
  Read a keypress and return the resulting character.  Nothing is
  echoed to the console.  This call will block if a keypress is not
  already available, but will not wait for <kbd>Enter</kbd> to be pressed.
  If the pressed key was a special function key, this will return
  <code>'\000'</code> or <code>'\xe0'</code>; the next call will return the
  keycode.  The <kbd>Control-C</kbd> keypress cannot be read with this
  function.

  Similar to <tt class="function">getch()</tt>, but the keypress will be echoed if it 
  represents a printable character.

<dd>
  Cause the character <var>char</var> to be ``pushed back'' into the
  console buffer; it will be the next character read by
  <tt class="function">getch()</tt> or <tt class="function">getche()</tt>.
